I've only had four of these, one still remains in my collection. I assure you, this is not a Master, although many have been mistaken as one. After having the distinct privilege of being invited to the home of Dani and Ernie Kirk, not once, but twice during my recent visit to Seattle-I was able to bring my two to them for confirmation. This is a rather nice example with a heavier design. Others I have seen can be more white on the surface. All share the same distinct property of a transparent red glass base. You will also notice the seams on them although similar to master, are absolutely Akro. One micro pin and a hint of pocket wear seen on her with perhaps a touch of silvering at one of the seams.
